Which type of distribution system is most suitable for multi-storey building ? Correct Answer Raising mains

Raising mains is the most suitable type of distribution system for multi-story building.

Types of distribution systems:

1.) Raising mains:

  • In this type of distribution system, many branch lines are taken out from the mainline.
  • Each branch line works as a separate circuit.
  • On each floor, the raising mains are connected to the sub-main board through proper cable termination.

2.) Busbar chamber:

  • Busbar Chambers are the metallic strips or bars, housed inside the switchgear, panel boards, and busway enclosures for high current power distribution and to ensure straightforward network configuration.

3.) Radial distribution:

  • This system is used only when a substation or generating station is located at the center of the consumers. 
  • In this system, different feeders radiate from a substation or a generating station and feed the distributors at one end. 
  • Thus, the power flow in this distribution is in only one direction.
